Question 1

What is SVG?

Accepted Answer

SVG (Scalable Vector Graphics) is an XML-based vector image format. Unlike bitmap formats like PNG and JPG, SVG uses mathematical formulas to describe graphics, allowing infinite scaling without loss of quality. SVG files are small, editable, and support animation and interactivity. They are widely used for web icons, logos, and data visualization charts.

Question 2

What is the difference between SVG and Canvas?

Accepted Answer

SVG is a vector graphics format based on XML, describing each element individually with DOM support, event binding, and CSS styling — ideal for icons and logos that need scaling. Canvas is a pixel-level drawing API controlled via JavaScript — suited for games, complex animations, and large data visualizations. SVG stays sharp when zoomed in, while Canvas becomes pixelated. SVG performance degrades with many elements, while Canvas handles large pixel counts more efficiently.

Question 3

How do I use SVG in a web page?

Accepted Answer

Several methods: 1) Inline SVG — embed SVG code directly in HTML for full CSS/JS control; 2) img tag — `<img src="image.svg">`, simple but no internal element access; 3) CSS background — `background-image: url(image.svg)`; 4) object/embed tags. SVG files exported from this tool work with all of these methods.

Question 4

Why does SVG to PNG conversion fail?

Accepted Answer

Browser Canvas security policies may block some SVG content: 1) SVG references external images (cross-origin) — causes security errors; 2) SVG uses unsupported features; 3) SVG code has syntax errors. Ensure your SVG code is correct, avoid external resources, and use standard SVG elements.
